Enabling the Router to look up the sender's Internet address from the Person document

When a Notes® client is configured to send mail for Internet recipients in Notes rich text format, a Domino® server must convert outbound mail from the client to MIME format for Internet mail transport over SMTP. The Domino server responsible for the conversion must ensure that all addresses in the message headers, including both the recipient and sender addresses, are in Internet mail (RFC 821/822) format.

About this task

If the sender's Location document specifies an Internet address, Domino places this address in the From field of the MIME message. However, if the Location document does not specify an Internet address, Domino must obtain the address by other means. By default, Domino forms an Internet address by converting spaces in the user's Notes address into underscores, and prefixing the names of Domino domains in the address with percent signs. For example, a Domino server in the renovations.com Internet domain converts the Notes address John Smith@Notes to the Internet address John_Smith%Notes@renovations.com. Domino determines the Internet domain from the Server document or the Global Domain document.

If your organization prefers to standardize Internet addresses using a format that does not reveal internal domain names, you can specify an Internet address in each user's Person document and configure Domino to look up the specified addresses during MIME conversion.


  1. Make sure you already have a Configuration Settings document for the server(s) to be configured.
  2. From the Domino Administrator, click the Configuration tab and expand the Messaging section.
  3. Click Configurations.
  4. Select the Configuration Settings document for the mail server or servers you want to administer, and click Edit Configuration.
  5. Click the MIME > Conversion Options > Outbound tab.
  6. For the field Lookup Internet address for all Notes addresses when Internet address is not defined in document, choose one:
    • Enabled - On outbound Internet messages, if the address of the sender or any recipient is in Notes format, Domino looks up the user's Internet address from the Person document and, if found, substitutes it for the Notes address before sending.
    • Disabled - (default) Domino forms Internet addresses based on rules in the Global Domain document. If a Global domain document is not present, Domino constructs addresses by converting spaces into underscores and encoding Domino domains with percent signs. For example, Domino converts the Notes address John Smith@Notes to the Internet address John_Smith%Notes@renovations.com
    Note: When this option is disabled, Domino will continue to perform Internet address lookups if configured to do so in the field Internet address lookup in the SMTP Address Conversion section of the Conversion tab of the Global Domain document.
  7. Click Save & Close.
